An innovative optical design, which includes three Super ED (extra-low dispersion) glass elements and one ED glass element, reduces axial chromatic aberration as well as lateral chromatic aberration. The impressive resolution and contrast are maintained up to the edges of the image, allowing for greater flexibility in cropping and editing.

Enhancing the effectiveness of Sony's original Nano AR Coating II, reflections within the lens body are carefully controlled to minimize glare and ghosting for clear, sharp images.

The speed and accuracy of autofocus tracking are maintained even during continuous burst shooting at a small aperture of F22. The user can perform continuous shooting with panning to follow moving subjects or can remain stationary to achieve greater depth of field without worrying about the limitations of the minimum aperture.

An optical design that includes Super ED (extra-low dispersion) glass elements has reduced the subjective weight by using fewer elements near the front of the lens. This optimizes balance and reduces inertia, which is felt as resistance to rotation, allowing precise, flexible lens movements and camera shifts during shooting.

The SEL300F28GM includes a function ring that can directly control Power Focus dynamic focusing, APS-C/Full-frame switching, or compatible body preset focus functions. Power Focus: This is the default setting. Rotating the ring initiates steady speed focusing in the specified direction. APS-C/Full-frame: When assigned to the corresponding body menu function, rotating the lens immediately selects APS-C or Full-frame format. Preset Focus: Available only with the a9 III. Rotating the ring in either direction selects the corresponding preset focus point. The preset focus function is not limited by the focus range limiter switch settings.

The SEL300F28GM can use a standard ND insert with a diameter of 40.5 mm and other filters, as well as Sony's VF-DCPL1 circular polarizing filter. As with other features, the new lens hood design includes highly durable plastic in its construction, offering the ideal combination of durability and low weight. An exclusive soft case is also provided to protect the lens from shocks. Additionally, a lens strap is provided.
